Abstract
Given the continued high prevalence of mosquito-transmitted diseases there is a clear need to develop novel disease and vector control strategies. Biopesticides of microbial origin represent a promising source of new approaches to target disease transmitting mosquito populations. Here we describe the development and characterization of a novel mosquito biopesticide, derived from an air-dried, non-live preparation of the bacterium Chromobacterium sp. Panama (Family: Neisseriaceae). This preparation rapidly and effectively kills the larvae of prominent mosquito vectors, including the dengue and Zika vector Aedes aegypti, and the human malaria vector Anopheles gambiae During semi-field trials in Puerto Rico, we observed high efficacy of the biopesticide against field-derived Ae. aegypti populations, and against Ae. aegypti and Culex spp. larvae in natural breeding water, indicating the suitability of the biopesticide for use under more natural conditions. In addition to high efficacy, the non-live Csp_P biopesticide has a low effective dose, a long shelf life, high heat stability, and can be incorporated into attractive larval baits, all of which are desirable characteristics for a biopesticide.Importance We have...
